NAME¶
CURLOPT_CERTINFO - request SSL certificate information
SYNOPSIS¶
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_CERTINFO, long
certinfo);
DESCRIPTION¶
Pass a long set to 1 to enable libcurl's certificate chain info gatherer. With
this enabled, libcurl will extract lots of information and data about the
certificates in the certificate chain used in the SSL connection. This data
may then be retrieved after a transfer using curl_easy_getinfo(3) and
its option CURLINFO_CERTINFO(3).
AVAILABILITY¶
This option is supported by the OpenSSL, GnuTLS, NSS and GSKit backends.
RETURN VALUE¶
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
